IMPROV EMENT IN STOVE-PIPE THIMBLES.

Specification forming part of Letters Patent No. 217.233, dated July 8,1879 application filed April26, 1879.

To all whom it may concern:

Be it known that I, MICHAEL MCQUIRE, of Baldwinsville, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Stove-Pipe Thimbles, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to stove-pipe thimbles designed to be adjustableto the thickness of the wall or ceiling to be penetrated by thestove-pipe; and it consists in a novel construction and combination oftelescopic cylindric sections provided at their respective outer endswith a collar, and connected with each other by tension-springs, all ashereinafter more fully described.

The invention is fully illustrated in the accompanying drawings, whereinFigure 1 is a longitudinal section of the stove-pipe thimble partiallyextended; Fig. 2, an end view of same, and Fig. 3 a transverse sectionon line a: a: in Fig. 1.

Similar letters of reference indicate corresponding parts.

A A are two annular rims, constituting the abutting shoulders or collarsat the ends of the thimble. Each of the said rims is provided on itsinner surface with an annular flange, a, concentric with the centralopening of the rim, and at the outside of the said flange are slots orapertures I) through the rim. To each of the rims A is connected aseparate cylinder, C, which is fitted to the exterior of the flange a,and provided at its end with tongues or prongs 0, extending through theapertures b in the rim and clinched upon the outside thereof.

The flange a of one rim is larger in circumference than that of theother rim, so that the cylinder connected with the former is alextendedtension-springs s, which yieldingly draw the cylinders toward eachother, and

allow them to be extended according to the thickness of the wall orceiling to which the thimble is to be applied.

"Having described my invention, what I' claim is- The combination of therims A A, provided, respectively, with the annular flange a, slots 11,and ears (I, the telescopic cylinders C C, fitted to the externalperiphery of the flange a of their respective rim A, and having tongues0 extended through apertures or slots b and clinched upon the outside ofthe rim, and the springs 8, connected at their ends, respectively, withthe ears of the two rims, all constructed and combined substantially asdescribed and shown, for the-purpose set forth.

In testimony whereof I have signed my name and affixed my seal in thepresence of two attesting witnesses at Baldwinsville, in

the county of Onondaga and State of New- York, this 21st day of April,1879.
